Heads-Up Display Turns Car Into Fighter Jet

Posted on by

While most of us will never set foot in a fighter jet, some of us can still try to get as close as possible. One of the most eye-catching features of a fighter jet (at least from the pilot’s point-of-view) is the heads-up display, so that’s exactly what [Frank] decided to build into his car to give it that touch of fighter jet style.

Heads-up displays use the small reflectivity of a transparent surface to work. In this case, [Frank] uses an LED strip placed on the dashboard to shine up into the windshield. A small amount of light is …read more

Hackaday Prize Entry: ESP32 Monster and Getting Started Quickly

Posted on by

Prolific hacker [kodera2t] is working on his own “ESP32 monster board” dev board for the still-newish ESP32 WiFi module. His board has everything: Ethernet, OLED, LiPo, and even CAN-bus. But all that peripheral connectivity is worth nothing if you can’t program the microcontroller to use it.

The Arduino environment for the ESP32 is coming along quite nicely, but it’s not yet fully featured enough to run all of [kodera2t]’s hardware. To take advantage of all that, he needs to use Espressif’s SDK — called the “IoT Development Framework” or IDF for short. In his latest project log, [kodera2t] goes through …read more

Hackaday Prize Entry: Modular Stepper Control

Posted on by

Stepper motors are a great solution for accurate motion control. You’ll see them on many 3D printer designs since they can precisely move each axis. Steppers find uses in many robotics projects since they provide high torque at low speeds.

Since steppers are used commonly used for multi-axis control systems, it’s nice to be able to wire multiple motors back to a single controller. We’ve seen a few stepper control modules in the past that take care of the control details and accept commands over SPI, I2C, and UART. The AnanasStepper 2.0 is a new stepper controller that uses CAN …read more

Building an OBD Speed Pulse: Behold the ICE

Posted on by

I am a crappy software coder when it comes down to it. I didn’t pay attention when everything went object oriented and my roots were always assembly language and Real Time Operating Systems (RTOS) anyways.

So it only natural that I would reach for a true In-Circuit-Emulator (ICE) to finish of my little OBDII bus to speed pulse generator widget. ICE is a hardware device used to debug embedded systems. It communicates with the microcontroller on your board, allowing you to view what is going on by pausing execution and inspecting or changing values in the hardware registers. If you …read more

Reverse-Engineering the Peugeot 207’s CAN bus

Posted on by

Here’s a classic “one thing led to another” car hack. [Alexandre Blin] wanted a reversing camera for his old Peugeot 207 and went down a rabbit hole which led him to do some extreme CAN bus reverse-engineering with Arduino and iOS. Buying an expensive bezel, a cheap HDMI display, an Arduino, a CAN bus shield, an iPod touch with a ghetto serial interface cable that didn’t work out, a HM-10 BLE module, an iPad 4S, the camera itself, and about a year and a half of working on it intermittently, he finally emerged poorer by about 275€, but victorious in …read more

Reverse Engineering the Smart ForTwo CAN Bus

Posted on by

The CAN bus has become a defacto standard in modern cars. Just about everything electronic in a car these days talks over this bus, which makes it fertile ground for aspiring hackers. [Daniel Velazquez] is striking out in this area, attempting to decode the messages on the CAN bus of his Smart ForTwo.

[Daniel] has had some pitfalls – first attempts with a Beaglebone Black were somewhat successful in reading messages, but led to strange activity of the car and indicators. This is par for the course in any hack that wires into an existing system – there’s a high …read more

Tesla Hack – Remote Access Whilst Parked or Driving

Posted on by

The big buzz on my Twitter this week was about the Tesla Hack carried out by a Chinese crew called Keen Security Lab. It’s no big surprise even though Tesla is known for being fairly security concious and proactive about it. With it being a connected car, that’s pretty important that any remote control capabilities […]
